I have a Raspberry Pi 3 B+ (Linux raspberrypi 4.19.58-v7, Raspbian GNU/Linux 10 (buster)). I am able to browse the internet through the Chromium Web Browser to websites like Google.com and Yahoo.com, but I cannot access GitHub.com. What I remember at one point is that I might have uninstalled or done something with Git when I uninstalled PiVPN. But when I installed Git again, the terminal said there's nothing new to install, so it must already be on my Raspberry Pi. Please help and thank you!
